Benefits of technology

Enables accurate, real-time monitoring of particle size, reducing waste and increasing efficiency by allowing for immediate adjustments in processing, thereby improving the quality and consistency of ground products.

Problems solved by technology

However, it does not discuss measuring particle size.
U.S. Pat. No. 8,401,271 discloses measuring various characteristics of seeds based on image data, but does not disclose the measurement of the average particle size of particulate products.
However, this reference does not disclose the determination of particle size from a population of particles.
Current methods for NIR spectroscopy do not provide for accurate, real-time assessment of the average particle size for particulate products.

Development of Particle Size Calibration for Real Time Measurement in the Feed Mill

[0121]A ProFoss inline NIR was installed in a location which directly followed the hammer mill. Although a hammer mill is exemplified in this Example, any mill that comminutes a product may be used. The computer that stored the data was placed in the mill control room linked to the NIR machine by fiber optic cable. Over an 8 week period, samples of particulate grain (corn and wheat) were collected in duplicate every hour while simultaneously pushing a button on the NIR machine in order to correspond the sample taken with the wavelength spectral information read at the time. For data collection timeline and double sampling protocols (e.g., FOSS PROTOCOL), samples were analyzed in a QA Lab to determine grind size, and a calibration was developed for the NIR machine. The calibration was downloaded on the NIR machine and tested by continuing to double sample for an additional 4 week time period. An analys...

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is the U.S. National Phase of International Patent Application No. PCT / US2015 / 035562, filed Jun. 12, 2015, which claims the benefit of priority to U.S. Provisional Patent Application 62 / 012,725 filed Jun. 16, 2014, the contents of each are hereby incorporated by reference in their entireties.FIELD OF THE DISCLOSURE[0002]The present invention relates to a method and system for in-line analysis of particles flowing in a moving stream.BACKGROUND OF THE INVENTION[0003]Near-infrared (NIR) spectroscopy is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from about 800 nm to 2500 nm). Instrumentation for NIR spectroscopy comprises an infrared light source, a detector, and a dispersive element (e.g., a prism, a diffraction grating) to allow the intensity at different wavelengths to be recorded. Fourier transform NIR instruments using an interferometer are also used, especially for wavelen...
